Palpebral arteries
Anterior view of right eyelids
The margins of the lids, the tarsal plates and the conjunctival sac have been exposed. The orbital roof and levator palpebrae superioris muscle have been cut away and the orbital fat removed.
  1. Superior oblique muscle (tendon removed)
  2. Right pointer: Ophthalmic artery (in depths of dissection) Left pointer: Sclera
  3. Conjunctiva (outer surface)
  4. Upper pointer: Superior tarsal arch (peripheral arcade) Lower pointer: Superior tarsus
  5. Superior tarsal arch (marginal arcade)
  6. Skin of lid margin
  7. Lateral palpebral branch of lacrimal artery
  8. Superior tarsal branch of zygomatico-orbital artery (this vessel has only minute branches communicating with lacrimal artery (7)
  9. Orbital margin (cut across)
  10. Lateral palpebral raphe
  11. Lateral palpebral branch of zygomatico-orbital artery
  12. Inferior tarsal branch of zygomatico-orbital artery
  13. Inferior tarsus
  14. Upper pointer: Palpebral cunjunctiva (outer surface) Lower pointer: Sclera
  15. Orbicularis oculi muscle
  16. Orbital branch of transverse facial artery
  17. Infraorbital margin
  18. Orbital branch of infraorbital artery
  19. Frontal artery
  20. Supraorbital vein
  21. Small artery which enters osseous canal in frontal process of maxilla
  22. Dorsal nasal artery
  23. Upper pointer: Middle palpebral artery (superior) Lower pointer: Medial check ligament
  24. Middle palpebral artery (inferior)
  25. Arterial branch to lacrimal caruncle
  26. Medial palpebral ligament
  27. Area of origin of orbicularis oculi muscle
  28. Arterial branch to lacrimal sac
  29. Inferior tarsal arch (marginal and peripheral arcades are present but not as well defined as in upper eyelid)
  30. Left pointer: Anterior ciliary artery Right pointer: Inferior rectus muscle
  31. Inferior oblique muscle
  32. Angular vein
  33. Angular artery
